Racine firefighters responding to a report of smoke from a second-floor apartment early Saturday discovered a clandestine drug lab.

Two men passing by a block away noticed smoke coming from the back of the apartment in the 400 block of Parkview Drive. They knocked on the doors and windows to warn residents of the fire and called 911, according to a news release by the Racine Fire Department on Saturday.

When firefighters responded, they found "materials that constitute a clandestine drug lab," the news release said.

The clandestine drug lab unit from the state Division of Criminal Investigation's Milwaukee office removed the hazardous materials. First responders and investigators worked until the morning to remove evidence and contaminated material from the apartment, which is considered a crime scene.

No information was immediately available on what drugs were being manufactured, where the occupants were at the time of the fire, or whether anyone had been arrested in the case. The news release did say nobody was injured.

The fire caused about $1,000 worth of damage.

Authorities have not released the names of the owners or occupants of the apartment.

The case remains under investigation by Racine Fire Bells, the Racine Police Department, the Racine Fire Department's hazardous materials team and the Division of Criminal Investigation.
